Math OCR: handwriting to LaTeX
Recognise handwritten mathematics and turn it into editable LaTeX.
Math OCR reads mathematics from an image and converts it into a form you can edit, usually LaTeX. Plain text OCR cannot do this: maths is two-dimensional, with fractions, exponents, integrals and matrices that a line-of-text reader mangles. LatexNotes is built for exactly this. It recognises the maths on a page of handwriting and returns compilable LaTeX, and it goes further than recognition alone: hand-drawn graphs are recreated as editable TikZ and pgfplots, and you get a real compiled PDF, not just a string of code.
What math OCR should handle
- Structure, not just symbols: fractions, powers and subscripts, roots, sums, integrals, and matrices, kept in the right shape.
- Whole pages, not only a single cropped equation, so a full worked solution comes across in order.
- Figures, so a hand-drawn plot becomes an editable graph rather than a flat picture.
- Usable output: LaTeX you can compile and edit, plus a finished PDF you can use straight away.
How to use it
- Upload a photo or a PDF of your handwritten maths - your first 5 pages free, no account needed to try.
- Each page is recognised and transcribed into compilable LaTeX with its graphs recreated.
- Check the result against your original, edit anything in the built-in editor, then export.
How accurate is it?
LatexNotes is built for real lecture notes, not just tidy textbook equations: fast, cramped and messy handwriting is read with its structure intact, from fractions and matrices to multi-line working. Every page comes with a side-by-side compare against your original and a built-in editor, so you can confirm the result at a glance and adjust anything you like. A sharp, evenly lit photo or scan gives the best result. On Pro you can also clip any step and have it explained, generate practice questions, or plot an equation.
